The Percents API lets issuers integrate card linked offers, cashback, and branded rewards. Branded balance is merchant-scoped value that a cardholder earns with a merchant and can later spend at that merchant when the balance is available and eligible.
Use https://sandbox.percents.com for testing. Production uses https://prod.percents.com.
Start with the Integration Path for the issuer workflow, or go directly to the API Reference when you are ready to implement.
